ANTLR4 Toy language compiler that generates JVM bytecode
To build you'll need JDK 8 or newer. The build process is so simple that I've decided not to use any build tools.
To generate the parser code from the LANSet.g4 file run
./generateParser.sh
To build the compiler and generate the jar file run
./build.sh
If there are no errors you should have lans
6FDC
etc.jar in the current directory.
./runTests.sh
Let's create a file called example.lans and paste some example code:
programa example
escriureln("Hello world!");
fprograma
Compile it to generate example.class
java -jar lansetc.jar example.lans
and run it!
java example
You should see the familiar string printed in your terminal.
Exception in thread "main" java.lang.NoClassDefFoundError: org/antlr/v4/runtime/TokenSource- The jar needs to have access to lib/antlr-4.9.2-complete.jar in the current folder.
